A method of making an amino-alkylenediol and intermediate compounds useful in the method is disclosed. The method includes preparing a first intermediate compound comprising an aminoalkylene diol wherein a protecting group is linked to the amino functionality, and optionally, preparing a second intermediate compound comprising a salt of the first intermediate compound.
The first intermediate compound has the structure
wherein R is a divalent alkylene radical having from 2 to 20 carbon atoms, X and Y are independently a divalent linking moiety or a single bond, and Z is a protecting group.
The second intermediate compound has the structure
wherein R is a divalent alkylene radical having from 2 to 20 carbon atoms, X and Y are independently a divalent linking moiety or a single bond, TsO
−
is toluene sulfonate, and Z is a protecting group.
